How to Debug openjdk using gdb?

Question

I have built openJDK the debugging version with the following configuration options in README-builds

 bash ./configure ---with-debug-level=slowdebug --with-target-bits=64

However I cannot set any breakpoints or to be correct there are no symbols, doing some reseach on google I have found out that I should extract .diz (libjvm.diz) files in lib folder, but this does not seem to work.

diz stands for debugging information zip. Should be unzipped to be able to load debugging symbols with gdb. — Bionix1441

I will answer this for other people, after you get the sources Follow the steps:

bash ./configure --with-debug-level=slowdebug --with-target-bits=64 --disable-zip-debug-info
make all

An information worth mentioning that finally when you start the debugging session with gdb and you run the program you may see a SEGFAULT ignore it and continue till gdb stops at your breakpoint.
